Název v původním jazyce

Development of Coreus marginatus (Heteroptera: Coreidae) fed on seeds of Rumex obtusifolius.

Popis výsledku v původním jazyce

The length of the egg and larval development of Coreus marginalis was investiagted at constant temperatures od 19.2, 21.0, 25.0 and 28.8 C. For egg development, the lower developmental threshold (LDT) temperature was estimated to be 12.9 C and the sum of effective temperatures (SET) 142.9 day degrees (dd). The larvae were fed seeds of Rumaex obtusifolis. The mortality increased with decreasing temperature. Using data for the first three larval instars, where mortality was low, LDT was calculated to be13.9 C. No larvae completed development at 19.2 C and few at 21.0 C and 25.0 C. At 27.8 C, 75 % of the larvae completed their larval development. The SET for larval development was estimated to be 556 DD and SET for complete preimaginal development (ee +larva) 742 dd. The long developmental time and high larval mortality indicated that a diet consistinf only of R. obtusifolius seeds was unsuitable for the development of Coreus marginatus.
